PROBLEM TO BE SOLVED: To provide an air bag having a simple structure and a simple manufacturing process.SOLUTION: The air bag includes a first base fabric part, a second base fabric part superimposed on the first base fabric part, and constituting the outer shell of an air chamber part expanding and spreading when introducing expansion gas, together with the first base fabric part, and an adjustment member set in the inner part of the air chamber part and adjusting the shape of the air chamber part. The adjustment member includes a stem part, and a plurality of branch parts extending from the stem part. A first branch part and a second branch part in the plurality of branches extend from positions adjacent to each other. The first branch part is mounted on the first base fabric part and the second branch part is mounted on the second base fabric part. At least one branch part of the branch parts other than the first branch part and the second branch part extends from a position different in the stem part from the first branch part and the second branch part, and also is attached to either of the first base fabric part or the second base fabric part. |
